Barrage of Russian attacks aims to cut Ukraine's lights

In central Kharkiv you hear the rattle of generators on every street.

Ten days ago, Ukraine’s second city was plunged into darkness by a massive, targeted Russian missile attack on the energy system - it was the biggest since the start of the full-scale war.

As Kharkiv works to restore power, there has been a wave of additional strikes across the country targeting the energy supply.

Volodymyr Zelensky has condemned what he calls Russia’s “missile terror”.

The Ukrainian president has also renewed his calls to his country’s allies for more air defence systems as protection.

The authorities in Odesa on the Black Sea in the south of the country say the energy system there was the latest to be hit overnight, with missiles and drones, causing partial blackouts.

In Kharkiv to the north, the damage is more serious.

Kharkiv’s mayor, Igor Terekhov, has said it will take weeks to restore full supply and that is if Russia’s armed forces don’t strike the same targets again.

The initial attack on the city’s energy supply even knocked out the air raid siren. There is now a screeching noise that comes straight to people’s mobile phones instead.

There can be hours of those missile warnings in the city each day - during one on Saturday night, the blast wave from a strike blew out dozens of windows in a block of flats.

But the Russians have increasingly been aiming at the power grid.
